This started happening on my Android devices last night. Unfortunately, it cost me an hour or so of sleep because I started scrambling around changing my wifi network password then updating all the umpteen devices that connect to it. Then, when I got to work, NMS reported my work wifi as compromised as well! Seriously?!??
Turns out, it's a false positive alert due to a bug introduced in an application update that was published last night. It's since been fixed.
Norton Community post from Norton itself reporting the issue and its eventual resolution:

To fix the issue, go to Google Play, search for Norton Mobile Security and update the application. The annoying alerts should go away.
My name is Ed Bass. I'm the "Joe Normal" Ed Bass, because there's a philanthropic billionaire, movie director and musician with the same name. Google my name and you'll find all sorts of info about them. Me? I'm a computer engineer currently in the futures industry with very liberal social and political views. Let's see what I find interesting to post here......and if anyone actually reads it.
